no compression?

Re: no compression?

The valves / lifters / pushrods ... are they moving now when you turn the crank ??

Re: no compression?

sorry, i have to call you on that. According to my haynes, you shouldnt rotate the crank counter clock-wise, but I think it only means when its connected to the tranny. Its probably bad for the tranny

Sorry ... I didn't know you had the motor still in the car. I was assuming that you were doing a rebuild on a stand.

I am, I rebuilt it, its on a stand.
And yes, the lifters, pushrods, rockers are moving.. I was just freaking out (cause they were barely moving).

Another thing I dont have installed is the oil pan.

Oil pan doesn't make a bit of difference, BUT, the valves should be moving more than barely ... did you adjust the valve lash properly??

Re: no compression?

On 2002s you dont have to adjust valve lash right? arent the rockers auto-adjusting?
I guess I'm completely wrong, but I've never done it before.. lol
what time is it for you?

10:00am here in Italy ... I'm not sure if there's a difference between the 2000's and others, but I don't have a manual here at work ... :) Sorry.

Re: no compression?

You should be getting something even with the rings not seated up completely. If everything is moving as it should be, I don't know what to tell you, without looking at it.

There is no lash on the rockers because you have hydraulic lifters to take up slack.

Re: no compression?

did you remember to stagger the ring gaps on each piston

[slow6]

Re: no compression?

stagger?
the ring gaps are correct, the side clearance is correct, pistons are clean

Re: no compression?

stagger?
the ring gaps are correct, the side clearance is correct, pistons are clean

Upper ring and lower ring on opposite sides of the piston, not lined up.

Re: no compression?

the rings had so much side clearance that they were loose and freely able to move on their own. Plus the ring compressor moves the rings too
I'm sure I put them in right

Re: no compression?

Is the engine easy or hard to turn over?
Does it get harder to turn over before you hear the whoosing air?

[slow6]

Re: no compression?

yes it does
It sounds like the air is going through the rings into the crankcase

Re: no compression?

Check to see if its coming out the exhaust ports or not.
